This project is designed to improve power quality and to reduce current type harmonics distortion and power factor correction in domestic non-linear loads with the help of Vienna rectifier (three phase three level three switch pulse width modulation rectifier). Harmonics distortion in the electric distribution system is increasingly growing due to the widespread use of non-linear loads. Most modern power supplies are non linear load which contains electronic devices that do not conduct current over the full cycle of the applied voltage and so introduce harmonics in to the power network. Hence improve the power quality and gives unity power factor from the supply side. The paper compiles and discusses the harmonics reduction method, power factor correction, and power quality improvement technique. The simulation and experimental results demonstrate that the proposed system reduces current type harmonics distortion and power quality improvement in an efficient way.
